(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

a)Find the equation of the tangent line to f(x) = (x - 6)^8 at the point where x = 7.

b)The demand curve for a product is given by

q = f(p) = 5,000e-0.30p,

where q is the quantity sold and p is the price of the product, in dollars. Find f(6) and f'(6).

2. Relevant equations

a)sustitute x for 8

b) to find F(6) i sutitute p for 6

to find F'(6) i sustitute p for 6????

3. The attempt at a solution

a)the solution is 1 and this is incorrect

b)in F(6)=826 this is correct

in F'(6)=247.94 this is incorrect
